When dealing with transcendental functions, you should be able to obtain all
roots using the command "Reduce" instead of "Solve". Therefore, given that
0 < x <= 2 Pi, try the following command:
Reduce[6*Cos[x] - 5*Cos[x] == 0, x]
Hope this helps,

This is probably totally elementary, but I'm stumped nonetheless.
Anyway, in Mathematica, how do I solve an equation with multiple periodic
functions within a given function domain bound?
i.e. How would I find all values of x given 6Cos[x]-5Cos[x] = 0 where
0<x<=2Pi ?
thanks
